Roy The chiral langasite Ba 3 NbFe 3 Si 2 O 14 is a multiferroic compound. While its magnetic order below T N = 27 K is now well characterized, its polar order is still controversial. We thus looked at the phonon spectrum and its temperature dependence to unravel possible crystal symmetry breaking. We combine opt… [Phys. Rev. B 92, 104302] Published Thu Sep 10, 2015
